# --description--

You don't always have to use pixels when sizing an element.

Create a new rule, `.three`, and set its `width` to `91%`.

# --hints--

You should use the `.three` selector.

```js
const hasThree = new __helpers.CSSHelp(document).getStyle('.three');
assert(hasThree);
```

You should set the `width` property to `91%`.

```js
const hasWidth = new __helpers.CSSHelp(document).getCSSRules().some(x => x.style.width === '91%');
assert(hasWidth);
```

Your `.three` element should have a `width` value of `91%`.

```js
const threeWidth = new __helpers.CSSHelp(document).getStyle('.three')?.getPropertyValue('width');
assert(threeWidth === '91%');
```
